coi-ING FOR WALLS.

SRECIFICATION forming part of Letters Patent No. 278,656, dated May 29, 1883.V

` Application filed January 1I, 1883. (No model.)

for 'the protection of walls constructed of .and preventing the ent-rance of moisture.

burned clay, in the form and `manner herein' after described. The coping constructed of baked clay is advantageous in' that it can be cheaply made in any required size and form, in that it will not oxidizeor corrode'and does Anot need painting for its protection, and particularly in that, unlike metal, it does not ap preciably expand or contract under. changes in the temperature, and consequently `has no tendency to work loose from the wall orto disintegrate the latter.

Referring to the accompanying drawings,

Figure 1 represents a perspective viewof a section of my coping in its most simple form. Fig. 2 is a perspective view illustrating the section of the coping adapted for covering the corner or angle of a wall. Fig. 3 is aperspective View of the coping with a chimney or base of a chimney formed thereon.` Fig. et is a`crosssection of the same, on the line a' x, as it appears when applied to a wall. f .Referring to Fi g. l, A represents the coping, which is preferably made in lengths'of two or more feet, and of a semicircular form in crosssection. At one end it is provided with a i `iiange or enlargement, a, designed to overlap the contiguous end ofthe next section, for the purpose of closing the joint between the two In making use of this coping it is applied lengthj wise upon the upper surface of the wall, and

secured thereto `by cement, mortar, or other suitable means. The' series of sections thusapplied will afford a perfect protection for the top of the wall, excluding moisture and rain therefrom, and preventing the wallfrom being destroyed or disintegrated by the action of frost. In place of the shoulder a, a separate collar or covering-piece may be employed, if preferred. For the purpose of covering the corners or anglesof walls, I construct the coping of a corresponding angular or curved form.

Fig. 2 represents a section having its two ends at right angles to each otherfor covering the corner of an ordinary wall. which the two ends stand in relation to each other may oe made to correspond with the angle in the wall to be covered. Where the walls join in a T form, the coping may be made of a corresponding shape.

Those sections of the coping which are to cover walls having a Vchimney thereon I con struct as representedrin Figs. 3 and 4, with the chimney-body or base for the chimney" molded `directly upon the coping, with a cen- The'angle at trai opening or iiue extending downwardthrough'the same.- Thesection thus constructed and applied to a wall serves effectuallly to prevent the entrance of Water around the base of the chimney at its junction with the wall, or at the junction of the roof with the chimney,

thus avoiding thegreat difficulty which is or diuarily encountered in making a close joint at the point named. V

l Vhen applied to a party or parapet wall, my coping is peculiarly advantageous, in that it may be arranged to overlap or cover the upturned edge of a sheet-metal roong, or of the dashing, in the manner represented in Fig.` 4,

thus effectually maintaining the closeness of thejoint between the roof and the wall.

I do not claim, broadly, a coping adapted to cover a wall; nor do I claim a coping composedy of metal or equivalent material liable to oxidation and to expansion and contraction under changes of temperature; but

What I do claim isl. The improved coping for Walls, composed of burned clay, having a chimney base or body formed integral therewith, substantially as described aud shown. i

2. As anew article of manufacture, a burned: clay coping for walls, adapted to cover the top and embrace the sides of the wall, and having in its middle a'chimney flue or opening. p

3. The combination of the wall, the sheetmetal roof having the upturned edge or lash-4
